After what seems like an eternity at 1490 Dayton Avenue, next to the Food Emporium/A&P, WGCH is moving to Lewis Street in central Greenwich. Also, Business Talk Radio is heading to Shippan Avenue in Stamford. The reason for WGCH's move according to Scott Fybush, the lease at the Dayton Avenue location, a former doctor's office, is about to run out. When that does, WGCH moves.
